Im not sure if Id trust the scan gauge unless you have the add on sensor ??
Mine usually reads EOT around 198-207 and ECT at 200-210. In town and HWY
Ive gotten both up to around 215-220 pulling a large trailer and beating on it. I dont run a fan because I rarely town.
However to my first comment, every once and awhile I will fire the truck up cold and EOT will read 70-75 (block heater plugged in) and Ive had the ECT read 220-230 at the same time. It will dance around a bit untill next key cycle.
Not sure how accurate it is because Ive had ECT say 250ish and the factory gauge had barely moved.
